I have them mounted on my Bents. Got a good deal on them with the ski, the Bents were drilled when they came and have screw threads. think they hold a lot better then just drilled holes.
most of the time I ski them center mounted. ive skied them for like 5 days this season, and so far I have nothing to say against them. they hold up pretty good and the damage is just cosmetic (chipping). I never had a prerelease or some other troubles. Im happy with them. I wouldnt have bought them if they werent in this set with the bents. I just dont need to change my bindings that often, cause the bents are super fun center mounted. i think for a ski like the fujas or a line blend the binding system would make more sense, then for a only pow oriented ski like the Hellbents.
My friend have some griffons on his invaders and never had troubles with them, I think its a pretty decent binding if you're not too heavy they're a good choice I would say.
For my person: I'm 190cm but just 75kg and my DIN is up on 8-9
Got them mounted on the rossi S3 koopman.
Got nothing against them, do their work just fine for me. But as above in this thread is said, i hope they will hold up well. Also got the cosmetic damage because it's plastic. A week ago a changed from position and the front of my binding didn't take the steel cabel(? dunno how you call this) with it. Hope this wil not happen during the skiing. I screw them back and it was fixed.
